SHANK-BUTTON.

"To all whom it may concern: 7

Be-it known that I, CHARLES .J. SPILL, a citizen ofthe United States, and; a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Shank-Buttons, of which the following is a specification.

The present invention relates to buttons, and particularly to buttonsprovided with shanks. I

In the prior art it has been customary to insert a pin through the hole in the button blank and then subsequently to bend the pin into the shape of a shank. This is objectionable because the pin is not held firmly in the button blank, and also because the pin is apt to become unbent when subjected to even a moderately severe strain. It has also been attempted to insert a looped doubleended member through the button blank and then clench the same in position to'hold' the pin and expanding the loop to form a shank. This is objectionable because the clenching operation cannot be performed if the button blank is of glass, agate, pearl, ivory, vegetable ivory or porcelain-which materials are those most commonly used in the manufacture of buttons. To utilize this method the button blank must be made of compressible material.

The object of the present invention is to overcome these various objections and to produce a shank button in which the shank is held firmly in position and will not become unbent when subjected to strains.

The invention further consists of a shank button comprising a button blank having a hole extending through fromthe face to the back of the blank, and a looped double-onded pin having means as a head on one end for engaging the face of the button blank, said loop being expanded on the back of the button'blank to hold the head against the face of the button blank and to form a button shank on the back.

In connection with the foregoing, one or more wedge-shaped portions are provided on the pin and the hole in the button is made tapered toward the back of the blank. Also the head on one of the free ends of the pin is offset laterally to cover the other free end.

Other features will appear as the specification proceeds.

tion is illustrated in a concrete and preferred form, butchanges may of course be made from the legitimate and lntendedscope of t -e invention as expressed in the appended claims.

In the said drawings: Figure 1 is a vertical sectional view through a button blank showing the pin inserted, and also the means for supporting the button blank. Fig. 2 is a view similar to Fig. 1 with the panded. Fig. 3 is a section of the line 3-3 of Fig. 2. Fig. 4 is a top view of Fig. 2.

indicate corresponding parts in the several views.

, 1 indicates a button blank preferably provided with a tapered hole 2, said taper extending toward the back 3 of the blank 1.

4 is a looped double-ended pin, preferably provided with wedge-shaped surfaces 5 and preferably having a head 6 on one of the free ends 7 of the pin 4, offset laterally as shown to cover the other free end 8 of the said pin. The said head 6 is adapted to engage with the face '9 of the button blank.

In practice the button blank 1 is placed on a suitable support 10, the pin 4 is then inserted through the hole in the button blank so that the head 6 engages with the face 9 of the button blank. The loop 11 of the pin is then expanded to form a shank 12 and at the same time acts to draw the free end 8 down through the hole 2 of the button blank, thereby wedging the pin in the said hole, and bringing the head 6 home against the face 9. Suitable means may be employed to hold the head 6 of the pin while the loop is expanded. The button blank is preferably of some incompressible material such as glass, agate, pearl, ivory, vegetable ivory or porcelain, and the pin is preferably of metal or other material capable of being bent.
